Serial No. 560,253.

(GRANTED UNDER THE ACT OF MARCH 3, 1883, AS AMENDED APRIL 30, 1928; 370 O. G; 757) This invention relates to portable lamps and has for an object to provide an easily portable lamp that may be disassembled and collapsed so as to occupy a minimum amount of space.

i A further object of this invention is to provide a lamp in which the shade and the base may be used as the container for separable parts of the lamp.

A further object of this invention is to provide a portable lamp that may be collapsed into a minimum amount of space so that it may be packed in a carrying case along with such other apparatus with which it may be 5 intended to be used.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter more fully described.

Reference is to be had to the accompanying drawing forming a part of this specification in which like reference characters indicate corresponding parts throughout the several views and in which:

Fig. 1 is a partly sectional view of the portable lamp constituting this invention;

Fig. 2 is aview on line 22 of Fig. 1;

Fig. 3 is a perspective view of the lamp in partly packed disassembled position;

Fig. 4 is a plan view of the lamp in compleicely disassembled and packed position; an

Fig. 5 is a perspective view of a carrying case containing a part of the lamps and other apparatus with which this lamp may be used.

There is shown at 10 the lamp constituting this invention which is, as will be seen, similar to a conventional desk lamp when in assembled position, as shown in Fig. 1. This lamp 10 comprises the base 11, the hollow flexible support 12, the adjustable connection 20, wire 25, the socket 13, shade 1 1 and the bulb 15.

The base 11 has a boss 16, screwed or otherwise affixed thereto near one edge thereof. This boss 16 has a threaded opening therein extending through the base 11 and the flexible support 12 has a threaded projection 17 adapted to be received in the screw-threaded open- 59 ing in boss 16. The other end of support 12 has a similar threaded projection 18 which is adapted to be received in an internally screwthreaded hollow projection 19 forming part of the connection 20. This connection 20 comprises two U-shaped members 21 and 22 pivoted together and adapted to be adjusted by the bolt and wing-nut 23', the projection 19 being an integral part of member 21. U-shaped member 22 has a hollow threaded projection 23 which is adapted to be received in the end of socket 13, this socket having a switch control as shown at 24. The wire 25 connected at one end of a source of electrical energy, not shown, passes through the hollow projection 23 into socket 13. If desired, wire 25 can be passed through and concealed in support 12, passing through the opening in the base 11 when the lamp is intended to be permanently used in one place.

The shade 1 1 has a hollow projecting tapered boss 26 therein, which will snugly receive the socket 13 therethrough in the position shown in Fig. 1, the bulb 15 being in the position shown.

In operation, the lamp in assembled position is as shown in Fig. 1. When it is desired to disassemble this lamp for easy transportation along with such other apparatus as may be desired, as shown in the carrying case 27. the bulb 15 is first unscrewed in a conventional manner. Member 21 may then be unthreaded from end 18 of the flexible support 12 and this support 12 is in turn unthreaded from the boss 16. The socket 13 may then be withdrawn through the boss 26 drawing the connection 22 and wire 25 therewith. The support 12 may then be curled up and placed in the shade 14: along with the bulb 15, socket 13, wire 25 and mem-.

ber 21.

The base 11 which, as will be seen in Figs. 3 and 4c. is circular and of the same size as the flange 28 on shade 1 1, is placed against the shade, the boss 16 being preferably turned inside the shade, and several clamps 29, preferably three, are placed about the edges of base 11 and flange 28 securely holding them together as shown in Fig. 4.

Thus it will be seen that the lamp 10 may be packed into a very compact unit occupying a minimum amount of space and, as shown in Fig. 5, may be placed in a carrying case along with any other desired apparatus With which it may be intended to be used or ob- 5 viously may be packed in this compact form for shipping or storage purposes.

It will be understood that the above description and accompanying drawing comprehend only the general and preferred embodiment of my invention, and that various changes in construction, proportion and arrangement of parts may be made Within the scope of the appended claim, and without sacrificing any of the advantages of my invention.

' The herein described invention may be manufactured and used by or for the Government of the United States for governmental purposes Without the payment to me of any royalties thereon.

The invention having been described, what is claimed is:

r A portable lamp comprising a substantially circular base, an internally threaded boss secured to said base eccentrically thereof, a flexible support, a threaded projection on said support adapted to be received in said boss,'said support having a similar threaded projection on the other end thereof, a connection comprising two U-shaped members adjustably pivoted together, a hollow projection on each member, one projection on the connection being internally threaded and ada ted to receive the threaded projection on the support, a light socket, the other projection on the connection being externally threaded and adapted to be received in a' threaded opening in the light socket, an electricity conducting means connectedto said socket through said latter hollow projection, ashade, a substantially circular flange on said shade, the outline of said flange and of said base being substantially equal in size, a hollow boss projecting externally of said shade,

said boss tapering internally and receiving and holding said socket therein, all of said separable lamp parts being adapted to be packed into said shade as a container and said base being clamped to the shade flange to act as a cover therefor.
